5.7.6 P-Tables
Data written to the P(Preset)-table falls into the following categories:
(a) Data entered by the user to control the program scan (repetition time) and serial
link operational data.
(b) Preset data values entered by the user for use in the program, and addresses P150
upwards.
(c) Storage of Printer Text Messages. The user should access printer text messages
through the editor system.
(d) Configuration of Verification I/O tables.
(e) GEMCAN I/O Scanner configuration, where GEMCAN is fitted, uses P73.
(f) FIP configuration, where FIP is fitted, uses P94 to P96
Note:
The FIP Module used with the GEM80-500 Controller has some differences from
that used for the GEM80-400 Controller (e.g. in the P-tables where P94 to P96
were P120 to P122 for GEM80-400).
The P-tables are not cleared at power-off or at halt/run transition, although a clear
store command will clear (P150 upwards). The content of the other P-tables can be
altered by over-writing. Like other data tables, the size of the P-table is derived by the
controller as described at 5.7.4 and Table 5-5.
The P-tables’ contents are detailed at Table 5-6.
